When I checked mine it was 0.030" so it was off a good bit. I loosened the pump and advanced it until I got it to 0.050" or 1.27 mm and called it good. Threw it all back together and re bled it. It's running good now. I am gonna mark this for reference and do an 1/8" bump here soon. Also gonna mess with the full power screw. I need to get a new fuel pin and governor spring while I'm at it. I'm ready to burn rubber!

Im going to stop a Summit in Georgia on my way to Fl.

Get some steering u joints. I just realised in your thread that you had to use a gm box to fit the astro van u joints. My dodge box is new so I want to use it. Summitt has there house brand joints for $50. Not that bad I guess.

Re: 1955 12 Valve NAPCO Clone

Do y'all remember how I was saying things are going eerily good? Well I have been brought back to reality. I got the radiator installed and the belt put on. Also got the power steering fluid hooked up. I backed it out side little it run for about 10 minutes and then all the sudden it started missing. Barely ran for a minute and then died. It was acting like ran out of fuel. So I checked the fuel filter and it was full. I then pulled the feed to the pump and it was flowing a lot of fuel. When I went to crank it again I cracked the fuel lines and airiated fuel was coming out and it didn't have near the pressure it should. It will normally squirt all the way onto the fender. Now it is just bubbling out. I feel like something in the pump is the problem. Also it is leaking fuel out the vent on the diaphragm body. Anybody got any clues? It is so depressing

Re: 1955 12 Valve NAPCO Clone

Check to make sure the fuel shut off solenoid isn't pulling the plunger half way up. If you remove the sol, you can remove a plunger that's below the sol. Then put the sol back on to seal the pump. You then have to use the mechanical lever on the side of the pump to shut it down. Maybe try that and see what happens.

Re: 1955 12 Valve NAPCO Clone

I removed the little plunger from the ful solenoid and reinstalled it and it is still doing it. I forgot to say that. Any other ideas?

Re: 1955 12 Valve NAPCO Clone

If I had an extra pump, I'd send it to you. If you needed a p-pump, I could help you out.

Re: 1955 12 Valve NAPCO Clone

Are the VE pumps hard to rebuild? And do you have a p pump setup?

Re: 1955 12 Valve NAPCO Clone

Here is a little update from the weekend. I got a 55 seat from a good guy from down in Birmingham that helped me out. Needless to say I didn't get much done beside the seat. I was too depressed after the injection pump died on me. Still not certain if I am going to let a diesel shop rebuild it or if I will do it myself. I cannot stand letting someone else work on my engines or transmissions.

You can't see the bench bolted in there very good but I am glad to have one now so I don't have to spend time making brackets.

Re: 1955 12 Valve NAPCO Clone

Have you been looking into what is involved in rebuilding the inj pump? I have wondered myself. Once mine is on the road and some bugs are worked out I want to do the fuel pin govenor spring etc.

Re: 1955 12 Valve NAPCO Clone

Just glancing at the photos I thought you were inventorying mouse turds....

If that is the original paint can you post the paint code off the door jamb data tag. Thanks is advance. No hurry.

Haha! I worry about them falling through the rusted floor so I have to keep a check on them. Are you talking about the interior paint or the green?

Exterior, should be a three number code on the big data plate (at least my 59 has one there).

Re: 1955 12 Valve NAPCO Clone

Orrie I haven't forgotten about you. I will get it tonight. That is not the original paint color though. You can see pieces of the original dark green under that paint. You can see pieces under the fuel filler neck.

I pulled the injection pump off last night and am going to tear it down tonight. Heres to hoping the problem is evident and cheap.
